wrong code execution

[pkdhake]

Code:

If Browser("name:= Welcome to Bugzilla").Page("title:=Welcome to Bugzilla").Link("test:=Log In","visible := true").Exist(10) then
        Call Fn_ParameterizeTest
        else
        Call fn_Logout
End If

Whats wrong with this code? When always I try this code it goes to false condition if though condition is true.
